CAR-TRUCK.

SPECIFICATION forming part Of Letters Patent No. 671,844, dated April 9,1901.

Application filed February 8, 1901. Serial No. 46,523. (No model.)

T all whom, it nfl/wy concern,.-

Beit known that I, CHARLES F.WEs'rLAKE, a citizen of the United States,residing at Granite City, county of Madison, State of Illinois, haveinvented a certain new and useful Improvement in Oar-Trucks, of whichthe following is a full, clear, and exact description, such as willenable others skilled in the art to which it appertains to make and usethe same, 1o reference being had to the accompanying drawings, formingpart of this specification, in which- Figure l is a top plan view of myimproved car-truck. Fig. 2 is a side elevational view, partly insection. Fig. 3 is an end elevational view, partly in section, of myimproved cartruck; and Fig. 4 is a vertical sectional view on line 4 4,Fig. l.

This invention relates to a new and useful 2o improvement in car-trucks,being designed particularly for use in connection with tenders forlocomotives, though it is obvious that with slight modiications thetruck can be adapted to freight and other cars. z5 The object of theinvention is to construct a truck-frame which is simple, being composedof few pieces, and which is also extremely strong.

With this object in view the invention con'- sists of the construction,arrangement, and combination of the several parts, all as willhereinafter be described, and afterward pointed out in the claims.

In the drawings, A indicates the side frame 3 5 of the truck, which ispreferably made up of a casting, the upper edge of said side framehaving an inwardly-extending flange on, extending throughout the lengthof said side frame.

This side frame is made deepest at its middle" 4o portion, the endsbeing relatively shallow to accommodate the journal-boxes. The top angea is integral with vertical end flanges a', to which latter are joinedthe bottom flanges a2.

a3 indicates strengthening-webs integral with the iianges a and a* andthe main web of the side frame, said strengthening-webs 0,3 beingpreferably located above the journalboxes to strengthen the casting atthis point.

5o The anges are also provided with suitable openings to receive thecolumn-bolts by which the journal-boxes are'secured in position.

a4 indicates fins or webs preferably integral with the top flange andmain web of the side frame, said fins terminating above the bot-tomflange 0Lv2 to enable the proper manipulation of rivets, which securethe tie-bar in position. The main web of the side frame may be lightcnedby removing material therefrom at appropriate places.

B indicates transoms, which are shown in the drawings as beingZ-shaped,with their top iianges presented outwardly. These transoms arepreferably cast, and the top flanges b at the ends thereof diverge orwiden to some considerable extent in order to accommodate a row ofattaching-rivets passing therethrough and through the top flange a ofthe side frame. The vertical webs of the transoms are attached to thefins a4 by suitable rivets, 7o whereby a very rigid connection is madebetween the transoms and side framing. These transoms are preferablymade shallow at their middle portions and deepest at their ends and areso constructed as to provide guiding-ribs b for the bolster C. Thisbolster C is shown as being made in one piece and provided with suitablespring-seats for the accommodation of elliptic springs D, whilespring-seats E are riveted to the lower edges of the transoms 8o forsupporting said springs. These springseats E are strengthened by websand flanges appropriately placed and disposed, as shown.

` While I have described a construction having a slat spring-seat, it isobvious that a stirrup could be employed in connection with said bolstershould it be desired to use my improved truck-frame in connection withthe well-known type of swing motion bolster. Furthermore, instead ofsupporting the bol- 9o ster on springs the side framing could beprovided with pedestal-jaws for the reception of the journal-boxes,above which the springs could be used, as is well understood; also,

while I have described my improved side frame and transoms as being madeup of castings, preferably of steel, it will be understood that the samecould be formed of malleable iron, or sheet metal could be used by beingpressed or bent into shape. However, Ioo

I prefer to use east-steel, asI the i-u-tegrality of parts obviates thenecessity for so many lrivets as are usually required in pressed-steeltrucks.

I am aware that minor changes in the construction., arrangement, andcombination of the several parts'of my truck can be made and substitutedfor those herein shown and described without in the least departing fromthe nature and principle of my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a car-truck, the combination with the side frames, of transomshaving their top flanges presented outwardly, said lianges being widenedat the ends of the transoms and attached to inwardly-extending flangesat or near the upper edges of said side frames, substantially asdescribed.

2. In a car-truck, the combination with a side frame provided withvertical iins and an inwardly-extending top ange, of transoms having topflanges presented' outwardly, said flanges of said transoms beingwidened at the ends and riveted to the top liange of the side frame, thevertical webs of the transoms being riveted to the inwardly-extendingfins of the side frame, substantially as described?.

3. In a car-truck, the combination with a sidefranle made deepest atitsk middle portion,

provid-ed Witlran inwardly-extending marginal angepfstrengthening-webs;between said flanges above the journal-boxes,inwardlyextending fins a4, transoms whose top flanges are widened attheir ends. and riveted to the top flange of the side frame, thevertical web of the transoms being riveted to said fins, and

a bolster supported between said transoms, substantially as described.

4. In a car-truck, the combination with a side frame made deepest at itsmiddle portion v.and provided with inwardly-extending marginal Iianges,of Z-shaped transoms having their top flanges presented outwardly andwidened at the ends, where they arer'secured to the side frame bysuitable rivets, the bottom flanges of said transom-s extending i-n`wardly and receding to the main web of the transoms near the endsthereof, and removable spring-seats arranged between theftran'- soms andshaped to accommodate said inwardly-extending bottom flanges,substantially as described.

In testimony whereof I hereunto affix my signature, inl the presence oftwo Witnesses, this 6th day of February, 1901.

CHARLES -T. WESTLAKE.
